'4 x 5 pressed into the Vdesired shape. The frame is made of -two sides or parts where the wheel i or pulley is intended to be placed, as shown im-Fig. *2, which may be connected or secured together by-rivets or bolts a.'. I make each 2o of the sidesof .the frame withtwo cups or ,depressions, as shown at A' and a'. The d epression or. cup'A' is larger than the cup or depression a and. is intended to'include or contain it within its circumferential limits.

z 5 When the sides of the hanger-frame areput together in position for use, these double cups or. depressions are intended to face or oppose each other, asshown im Fig'. 2.A I- arrange cup-shaped caps B, which maybe stamped or 3o pressed out of sheet-steel or similar material into the desiredshape. These caps are in' tended tof b 'e received and contained within the' larger cups or depressionsAand to bel heldin positionA bybolts or rivets b. When in 3 5 position for use, the cupsor depressions in the i caps face or oppo'se the smaller cups or depressions in the sidesof the frame, so as to make a chamber or raceway adapted to receive aseries of balls,1as` shown in Fig. 2. IThe wheel 4oor pulley is formed of three disksor piecesvQ, C', and c, made of sheet-steel Aor similar .materiah which permits the sides, C and C', of the --whe'el to 'be' stamped -or pressed into a cup-shaped form, with the cups or depres- 45 4sions facingor opposing each other, as shown in Fig. 2. 4The central'diskcof the wheel is serifno. 636.923. uro model.) f

of smaller diameter than the sides and pro` vided lwith an, angular' -hole c', preferably v made rectangulanas shown in Fig. '3. The axle of the wheel is formed of a pin D, carrying an angular block or nut D', made of a :size and-shape to fit the hole c' in the central disk ofl the wheel. This block or nut'is made fast'to the pinoraxle D and is shrunk,

pressed, or otherwise securely inserted in the `-hole c', so that in rotatingit will rotate the j disk., The sides ofthe wheel and disk are cqnnected or fastened together by rivets, as

shown in Fig. 2, so that-the whole forms a A Y wheel or pulley with theends of :the axle or pin projecting and forming spindles,as shown `in the drawings. -A series of balls E are arranged 'in 'the chambers or raceways formed betweenthe cups a' and the cup or depression in the caps B, and the ends or spindles of the pins D pass through holes in the inner the axle, so as t'o rest and ride upon the balls,

asfshownin Fig. 2. The parts are then attached or connected together by the rivet so that theywili form a completed structure. (Shown lin section in Fig. 2;) One side of the hanger-frame has a depending portion F, 4 .by which it' may be attached toa barn or 7 5 other door in the usual way. r

'face of the caps larger than the diameter of I lVhat I regard as new, and desire'to secure i by Letters Patenti?, is;

In a door-hanger, the combination of a wheel-frame .provided with-two internal cups on each side-one circumscribing the other-' facing .or opposing eachother, caps arranged within the larger cups land provided. with cupsy facing or opposing such smaller cups, balls arranged y between the cups in the caps vand the smaller cups in the frame,and a; wheell or pulley provided with an axle having it`s spindles resting and riding upon the balls,
